How to use BluetoothHeadset class via reflection

I want to use methods of BluetoothHeadset class in Android 2.0+. Here is my code:

    Class bluetoothHeadsetClass = Class.forName(\"android.bluetooth.Bluetoo         


        

Answer 1

Also tried invoking this by reflection. Ultimately gave up and used a broadcastReceiver instead.

Declare the following intent-filter

and in your Receiver in onReceive check for:

if ("android.bluetooth.headset.action.AUDIO_STATE_CHANGED".equals(intent.getAction())) {
  headsetAudioState = intent.getIntExtra("android.bluetooth.headset.extra.AUDIO_STATE", -2);
}

and save the int as a static variable. Access it anytime you want to know if BT audio is connected(1) / disconnected(0). Not pretty, but gets the job done.
